Solar System Simulator!

Try loading the 4-star ballet one and running it. After you run it, make the blue star weigh 220, turn up the "accuracy" meter, and run it again.

set the masses at 120, 220, 20, 420 and check out what eventually becomes a stable orbit, for the survivors.

Heh. A standard two-body ellipse.

When I do that, they wiggle all over for a while and then eventually three of them head offscreen. Is that the desired result?

Pretty much. It's really neat for the first minute!

Oooh. Same set up you had, but change blue and yellow to 125 instead, and watch until at least 85... it gets weird.

Do a custom three-body.

#1: Mass 100, position 0,0 velocity 0X,-100Y
#2: Mass 100, position 100X,0Y, velocity 0X, 100Y

(Those two will form a perfect circle orbiting in each other's orbit exactly. Which is pretty cool!)

#3: Mass 0.001, position 50X,0, velocity 0,0.

Body #3 is exactly in the middle, in the dead spot between the two primaries. Set the "accuracy" to maximum and start it up.

Looks normal, right? Wait 5 seconds.

Mass 100 for the two large bodies resulted in them flying off the map in opposite directions.

I set it to 200 and got the results I think you were looking for.

200 is what I meant.

And the moral is: we shouldn't be shooting too much metal off into space?

Love this. Thanks. I wish it supported:
- more bodies
- the ability for the viewport to remain centered on a body

I've seen a Java applet that does that, but it's a complete pain to use as the only interface for it was applet param tags in HTML.

Keen!

I got one star to draw a pentagon!

I'm glad someone finally did a flash version of this. Ah, childteenagerhood.
